LEG HOLDER.

Application filed March. 23,1927. Serial No. 177,667.

This invention relates ,tov adevice for holding the leg Yparticularly adapted ,for use in performingoperations and treatments of the body.l where it is necessary that the legs be held in accrtain position during the operation.

An vobject of the invention resides in providing a device of the above mentioned character ,in which suitable leg gripping mem! l bers having adjustable legengaging elements permitting the ready, application of the device to the leg and which includes mechanism for operating the leg holding members l'in desired position. through the proper relative adjustmentsof the members.

The invention further comjnehends the provision of suitable casing in which a pair of .leg holding members are slidably mounted for relative movement upon the operation of a suitable manually adjustable means, so as to hold the legs in a proper position of adjustment between engaging elements carried by the .holding members.

The invention further con'iprehends numerous other objects residing in the speciiic I construction and relation of the parts for carrying out the invention, which are more particularly set Vforth in the following description and claim directed to a preferred form of the invention, it being understood however, that various changes in the size, shape, and relation of the parts may be made without departing from the spiritA and scope of the invention as herein set forth.

ln the drawing forming .part of this application Figure 1 is a plan View of the device indicating diagrannnatically the manner in which it isapplied in use. 1

Fig. 2 is a view similar to Fig. 1, showing the casing in horizontal section for illustrating the mechanism to adjust the leg holding members.

Fig. Sis a sectional view taken on the line of Fig. 2.

Fig. 4 is a sectional view taken on the line 4-4of Fig. 1. 1

A casing is indicated at 1 which is preferably Ushaped in cross section, and open at the opposite ends, the bottom edges receiving a suitable cover plate 2 for cooperation therewith to form a rectangular housing to mount the remaining elements of the device in operative relation therewith. Suitable leg holding members 4, there beingtwo otsuch members used, are duplicatesmand have the similarly formedA ends reversed with respect to each other as shown in FiguQ;

One end of each of the, members is provided With a suitable rack 5 positioned in the easing 1 so that the racks of each inember are in opposed relation and intermeshed with-the operating pinion 6 carried by the rota-table shaft 7 mounted rotatably in the casing 1. beyond the casing, and is provided with the operating handle 8 so that the operating gear 6 may be suitably manually rotated'for.

sliding theinembers 4 in and'out of the casing in opposite directions.

The Vedgeportion of the members/.4 provided with the rack teeth are recessed as indicatedat 9 in Fig. 4 to receive the rguiue tongues 1t) mounted on the cover plate 2 of thercasing. This guide tongue 10 serves to form a guideway k11 for the major portion of each of the leg holding members in cooperation with theside -wallsof the casingl, as;

may be clearly ascertained from Fig. 4.

This will prevent any twisting of the leg holding members in any of the operative positions of adjustment thereof in the casing, and permit the ready assembling of the parts through the cooperation of the cover 2 in the casing 1.

The central portion of each leg holding member 4 is provided with a lateral curved extension 12 forming one leg engaging element on each member while the opposite free end from that formed with the rack 5 is formed to provide a supporting bar 13 for i the adjustable leg engaging velement 14.

Each of the elements 14 has a suitable head formed with an openingto slidably receive the supporting bar 13 and are adapted for interlocked connect-ion therewith, through the provision of a suitable set screw 15, in

the head of the element.

lThe upper` face of the casing 1 isslotted as indicated at 17 from the endportion to the central portion 'in alinenient'with each of the elements 12 in order to permit adjustment of the leg holding members so as to bring the elements on both members in adjacent relation when it is desired 'to hold the legs close together.

rOne side of the casing 1 as shown in Fig. 2 carries a suitable set screw 18 threadedly mounted therein and adapted to engage one of the members 4 in radial alinement with One'. end of the shaft T extends ion the operating pinion 6 so as to provide a binding action thereon in" order to lool: the elements i in any set position.

From the above description, it will be ap parent that a highly simple `and advantageous leg holding device has been provided by the present invention, in which the en-` raging elements 14. may be suitably adjusted on the bar 13 to lirst receive the leg, either below or above the knee in its preferred use of the device, and may then be adjusted to the approximate posit-ion shown in the drawing to retain the legs engaged between the elements 14 and l2 ot each leg holdingr member.

A Therenpon, the handle S may be rotated 'for rotating the operating gear G and through cooperation with the rarks 5 on the members 4 they may be slidably moved in the easing l toward or away from eaeh other7 Within the limit-s of movement provided by the length oi the raelr 5 in order to obtain the desired adjustment thereot, 'followhigi which the set screw 18 is turned inwardly f Within the casing to frietionally engage one of the members and loek the same against the pinion 6 which will automatically lool; the other member 4, and retain the parts set in adjusted position.

It -vill be further clear' that the cover El with the guide tongue pin provides a special cooperation with the casing l, lor housing the elenient 4 in slidablel relation with re speet to one another, and preventing a twisting iiovement thereof, in such a manner that the entire mechanism may be quickly assembled or disassembled in order that it may be stored in a relatively small space during transportation.

In this Way7 the invention is useful to doetors, surgeons and the like in performinel minor operations and treatn'ients in the patents homes, and the devine may be readily set up when desired.

l'rlaving thus described my invention, what l vlaim as new is device of the class described, Comprising a "1J-shaped easing!` a cover plate mounted on said easing and provided on the inside with a longitudinally extending `raide tongue, said guide tongue cooperating with the Casing to orm guideways therein, a pair of leg holdingr members slidably mounted in the guideways in said easing', rack members ltornied on the inner entlslo't' said le` holdingI members in opposed relation, an operatingl pinion engaged with the rack of said members, means carried by the easing for holding and rotating;f said operating pinion, means carried by the zasing for loekinfr said members against movement thereii'i, and relatively adjustable lef:r engaging elen'ients carried by said leg holding members In testimony whereof I atlix my signature.
